For Cb = 40pF, maximum is about
15kΩ ~ 20kΩ
NOTES:
8. Limits should be considered typical and are not production tested.
9. These are I²C specific parameters and are not tested, however, they are used to set conditions for testing devices to validate specification.
10. C_b is the capacitance of the bus in pF.
